macOS install to USB memory stick possible?

​

I have tried to install macOS to a USB memory stick without sucess so far.

It went to panic.

The attached is a photo of the panic.

It seems AppleAHCIDiskDriver is the cause,

so I guess dealing with memory stick is the problem.

​

Do we need a special attention for installing macOS to a USB memory stick?

​

Thank you very much!

Have a nice weekend :)

​

​

Details:

OpenCore 0.8.4

macOS 12.6 Monterey.

​

USB Memory Stick:

128GB Samsung SDXC with a non-brand USB adaptor.

​

Install media has experience to successfully install macOS to an internal SATA drive.

USBMap has been done.

It goes to very close to a successful install.

1. Install media has no problem to install macOS installer to the memory stick.
2. macOS installer has no problem to boot and finish it.
3. 2nd macOS installer boot and its process done successfully.
4. 1st macOS boot and settings are done.
5. the last and 2nd macOS boot ends with a panic above.

​

I gave tries several times and it always ended here.
